无法理解<A HREF>标记和javascript调用

Question

I have a php application in which the web page displayed to the user. The page has some links "Edit", "Rename", etc.

When the user clicks on the link a dialogbox prompts. The dialogbox is nothing but a HTML <div> form that gets instantly displayed when the user clicks on the "Rename" or "Edit" link.

When I looked at the html source code (i.e. view -> source in Internet Explorer) I found the following Javascript and HTML code

<a class="update renameButton" href="javascript:void(0);">Rename</a>

I'm unable to understand how the dialogbox gets promted with the above code.

I expected the code to be something like the following:

<a class="update" onclick='rename();' href="javascript:void(0);">Rename</a>

Can someone help me understand this?

Answer 1

Some JavaScript loaded from a <script> element probably binds an event handler function to the element.
